I am currently processing an insert in an Apex class and I am getting an error “Too many DML rows: 10001”.

I would like to process more than 10,000 data items, and I would like to do several inserts in a batch process, etc. How can I call the batch from within an Apex class?

Does anyone know how to INSERT or UPDATE more than 10,000 data items?

I tried processing in a schedule batch, but this time we wanted to call the batch within an Apex class, not a schedule batch, so we were not able to do the processing we expected.
